How to clean glass on samsung clx-3160fn - Samsung CLX 3160fn All-In-One Printer

Ok to clean glass get tough and do not wreck the machine, sounds bad but damage could occure if your not careful but forceful.
1)down load any faxes not printed or sent to your computer
2)turn unit off with power button
3)inside of paper exit opening in the upper left hand side push green slide lever towards the back of the machine,,this locks the scanner carage(you can also see the green lock through the scanner glass to the left of the scanning carage as you move the lock). I did this not to disturbe the scanning carage while cleaning the glass.
4)the lid to the scanning bed has to be removed by lifting the complete tray to it's limit and unplugging the data cable,,it is in the middle between the hinges(pinch the cable connector plug locks on both sides and pull out the connector. To release the rectangular hinges lift and tilt the complete unit further back toward the rear of the printer/fax machine. It should lift out and REMEMBER that rear tilt when replacing the fax/printer feed unit as the hinges don't just slide back in to the respective holes.
5)there are two screws near where the hing holes are on eather side of the scanner cover they must be removed.
6)NOW this is the tricky part with only your hands no tools,,,with a large amout of force lift the back corner of the scanner cover(this does not seem possable but lifting at the side of the machine the cover does have a slight lip to lift with and it makes tearable sounds of distruction BUT IF you lift each side near the rear upward for about 1/2inch at a time(side to side)"2 INCHES ONLY" total the cover will give enough room to CAREFULLY reach your hand under the scanner cover with a damp rag to clean the glass and dry with a lint free rag(micro fiber rags work). I used no cleaners at all but lint free is the ticket. DO REALIZE THE TRAY ONLY LIFTS UP ABOUT 2 INCHES from the rear and it should stay up at the 2 inch hight. The removal of the scanning cover would mean more dissasembly of the unit and I saw no need to go that far.
6)NOW to replace the scanner cover (hopefully you were carefull enough not to crack or break the glass as lifting unevenly or pulling upward more than 2 inches could be the end to your scanner. The trick to get the cover back down with the registration tabs into thier respective holes,,it helps to pull outward on the sides of the plastic body where the tabs have to drop down into,,the large taps at the rear are a little less co-operative but with a bit more force the back body will seperate slightly and the read pins fall into place.
7)put the screws back in, then the scanner cover hinges first and snap the data cable into place,,Don't forget to slide the scanner lock (green tap)towards you to unlock the scanning tray.
Good Luck, it sounds difficult and it might be but it can be done without damage. I'm sure a true service repair man would not like the method but my machine is near it's final useful days.
